I am working through the excellent Hands On Rust book. This teaches rust programming through the medium of game development. The initial chapters use bracket-lib as a game engine. I am using my NixOS laptop for this task, which is running unstable plasma6, under wayland.
When I cargo run the simple example, I get the following errors:
Failed to initialize any backend! Wayland status: NoWaylandLib X11 status: LibraryOpenError(Op
enError { kind: Library, detail: “opening library failed (libX11.so.6: cannot open shared obje
ct file: No such file or directory); opening library failed (libX11.so: cannot open shared obj
ect file: No such file or directory)” })
I suspect I need to add something to my devshell flake, but I am not sure what is missing and would appreciate any tips!
The flake looks like this currently:
{
inputs = {
nixpkgs.url = "github:NixOS/nixpkgs/nixpkgs-unstable";
flake-utils.url = "github:numtide/flake-utils";
rust-overlay = {
url = "github:oxalica/rust-overlay";
inputs = {
nixpkgs.follows = "nixpkgs";
flake-utils.follows = "flake-utils";
};
};
};
outputs = { self, nixpkgs, flake-utils, rust-overlay }:
flake-utils.lib.eachDefaultSystem
(system:
let
overlays = [ (import rust-overlay) ];
pkgs = import nixpkgs {
inherit system overlays;
};
rustToolchain = pkgs.pkgsBuildHost.rust-bin.fromRustupToolchainFile ./rust-toolchain.toml;
in
with pkgs;
{
devShells.default = mkShell {
buildInputs = [
rustToolchain
cmake
pkg-config
fontconfig
];
};
}
);
}
Thanks for reading.
